> Operators can (optionally) carry `TypeDescriptor` of its output, key and value types. These can be used to determine right coders for `PCollection`s during translation to Beam API.
> Another enhancements of coders resolution are desired:
>  * Allow API user to disable use of `KryoCoder` as fallback coder.
>  * Every automatically created `KryoCoder` needs to respects classes registrations provided by user.
>  * Automate creation of 'PairCoder' whenever needed.
